I have a 1A ticket (PNR 2244893039) by 12424 rajdhani from NDLS to NJP. This is an E-ticket and wait listed 1 &2. I would like to have the boarding station changed to Kanpur Central. However, the Counter clerk says that Boarding change can be done only for confirmed e-tickets. Is it so? Boarding change is allowed only 24 hours before departure of the Train. By the time the ticket gets confirmed, it will be too late for Boarding change !!!!
